My ring doorbell was working fine at a previous home. I now have two issues: 1) Sometimes it picks up motion and sometimes it doesn't - and/or it is taking a long time for it to notify me. People are ringing the doorbell before I get a notification that they've even pulled in the driveway). 2) Last night someone pulled in and sat in his car for a few minutes, and thenwalked into the house. It seems to have caught both because there were 2 events in history, but I didn't get any notification. I have reinstalled the app and checked everywhere I can find. I have an Android. I tried to follow the instructions for going to Menu\>Settings\>Alarm Settings, but my settings only have General and Location.
